1. Check that the tap is turned on and that the hose is not kinked and squished by the dishwasher.
2. Check screen mesh filet on the inlet hose and water inlet valve to make sure it is not blocked with sand.
3. Replace water inlet valve, resistance should be 3,9 kohm in 230v, 0.95 kohm in USA 120V.
If water is entering the dishwasher:
1. Check that the pressure chamber is not blocked.
2. Replace flow meter.
ASKO Dishwasher F40 Fault – Water Valve Leakage

Description:
No temperature increase detected in 10 minutes during heating phase.
Action To Take:
1. Check wiring.
2. Check thermistor resistance, 60 kohm at 20C/68F.
3. Check heater resistance, 2040W 230V = 25 ohm, 1600W 230V = 32 ohm, USA 1200W 120V = 12 ohm.
ASKO Dishwasher F42 Fault – Thermistor Fault
Description:
Fault F42 means that the main PCB is not receiving a signal from the thermistor.
Action To Take:
1. Check wiring.
2. Check thermistor resistance, 60 kohm at 20C/68F.

Description:
Fault F45 indicates that the main PCB has detected that the diverter valve is not changing position.
Action To Take:
1. Check for foreign objects in diverter valve.
2. Check diverter valve motor resistance, 230V = 8.5 KOHM, 120V = 2.6 KOHM.
3. Replace PCB.
